awn-extras-applets: shinyswitcher can nolonger drag drop program between workspace thumbnails

[collura]

description:
in fedora15 gnome3 gnome-shell with avant-window-navigator extras-applet
"shiny-switcher" the workspaces appear in the tray but cant drag programs among
the thumbnails but need to use clickmenu 'move to workspace' items instead of
just dragging.

it was suggested (https://bugzilla.redhat.com/show_bug.cgi?id=711035#c1)
that the ability had existed in awn but was recently lost
and that it should be filed here.

may have missed some but
dont see any duplicate bugs or docs / forum posts
so filing here as 'bug' instead of as a 'request for enhancement'.

steps to reproduce:
1. open program in gnome-shell workspace
2. open another program in another workspace of gnome-shell
3. try to drag program from one workspace thumbnail to another
       but it fails to move the program to the other workspace
